The presence of endoskeleton is characteristic of:

Here's the answer to Q.14. Q.14 The presence of endoskeleton is characteristic of: An endoskeleton is an internal skeleton, typically made of bone or cartilage, that provides support and protection. A) Invertebrata* is a diverse group, and most invertebrates do not have an endoskeleton. Many have exoskeletons or hydrostatic skeletons. B) Vertebrata* (fish, amphibians, reptiles, birds, mammals) are defined by having a vertebral column and an internal skeleton made of bone and/or cartilage, which is an endoskeleton. C) Insecta (insects) are arthropods, and they are characterized by having an exoskeleton* made of chitin, not an endoskeleton. D) Coelenterata* (Cnidaria) like jellyfish and corals have hydrostatic skeletons or external calcareous structures, not endoskeletons. Therefore, the presence of an endoskeleton is characteristic of vertebrates. The final answer is B That's 2 down. 3 left today — send the next one.
